Question Laptop ghost fan issue

hi ! i have an issue with my new Samsung 3 Series laptop. i know for sure the fan works : when the cpu and/or cpu get hot, the fan speeds up ! But i'm not satisfied with the way it's configured. (the temps are around 50 celsius at idle !!) And whatever program i get, i can't manage the fan speed !! the fan isnt detected at all !
Any idea ?

Check the BIOS if there are any fan settings there. Also, are you running windows 7 or 8? I think there's a Samsung Settings App in Windows 8 that lets you control your fan.

Use speedfan software...

SpeedFan - Access temperature sensor in your computer

The speedfan software doesnt detect the fan. And in the Samsung settings, i have a "silent mode" that changes the fan speed with 3 different settings : AUTO, LOW, DISABLED.
And it is disabled by default...
I'll check the bios and will tell you the results

Well... nothing in the BIOS. Guess what ! I was unable to access the BIOS when i turned on the PC ! No key proposition ! so i tried DEL, F2, F12... didn't work. I managed to access the BIOS by entering first the Win8 settings... so weird. (i'm sure i can enter the BIOS before Windows 8 starts but i didn't find the key...).
Anyway, the BIOS is so poor... i didn't find anything about ventilation... :(

Note that 50C CPU at idle is normal for mobile devices, at least with Intel CPUs. I'd actually leave it the way it is unless your laptop is heating up to the point you can't use it (e.g. keyboard gets hot).

Windows 8 is odd in that to make the PC cold-boot faster, it actually skips the BIOS prompt. You have to use RESTART from Windows 8, not shut down, and hold down whatever the BIOS key is throughout the entire time the PC is restarting. By "holding down", I mean the key is pressed the entire time.
Check your manual to find out which key you should be holding.

some fan modules do not have pwm. I realize this on my older hp laptop, its just two pins.
They are voltage controlled. i dont think there is any software for this.

I guess you have to open it and check for connection and its condition. You may need to ask for computer technician to do that.

Tons of people try to find ways to control their laptop's fans, and except for older Dell's, few software solutions succeed.
I have never heard of a laptop bios that lets you control fan settings, or even change anything useful... Don't invest a lot of time in it, just switch to a high quality thermal goo and save some time.
